How to Resolve COD Error Code BLZBNTBGS000003F8 ‘Server Disconnected’?

The COD error code BLZBNTBGS000003F8 causes players to disconnect from the server, interrupting the game. This usually happens because of a weak network or background apps running on your device.

Other possible reasons include server issues, incorrect DNS settings, or firewall settings that block the connection. Sometimes, outdated network drivers or problems with the internet service provider (ISP) can also trigger this error.

In this article, we will discuss different ways to solve this error.

1. Roll Back Network Driver

Sometimes, new network driver updates can cause problems with games, leading to connection issues. Switching back to an older driver version can resolve these problems and help your device connect better with game servers, ensuring a stable connection.

1. Press Windows key + R, type “devmgmt.msc”, and press Enter to open Device Manager. If prompted by UAC, click Yes.

   

2. In Device Manager, expand the Network adapters section by clicking the drop-down arrow.
3. Find your Killer E2200 driver, right-click it, and choose Properties.

   

4. Go to the Driver tab and click Roll Back Driver, then click Yes to confirm.

   

5. Let the rollback complete and restart your computer if needed.
6. After restarting, check if the issue is resolved.

2. Use a VPN

Using a VPN can help avoid regional network blocks or slow internet speeds from your ISP. By hiding your real IP and connecting through a different server, a VPN can make your connection to the game servers more stable, reducing disconnections.

7. Once downloaded, double-click the executable and complete the installation.

   

8. Sign in with the account you created. Click Start your free trial and choose a location outside Asia or Australia.
9. While the VPN is active, start the COD game to check if the issue is resolved.

3. Change the DNS server

Changing to a different DNS server can improve your connection to game servers. Opting for a reliable one, like Google or Cloudflare, helps avoid issues with your ISP’s DNS, cuts down on lag, and prevents connection drops. This tweak can result in smoother gaming.

1. Press Windows key + R, type ‘control.exe’, and press Enter to open the Control Panel.

   

2. Click on Network and Internet, then Network and Sharing Center.

   

3. Click on Change adapter settings.

5. Go to the Networking tab and double-click Internet Protocol Version 4 (TCP/IPv4).

   

6. Select Use the following DNS server addresses. Set 1.1.1.1 as the Preferred DNS Server and 1.0.0.1 as the Alternate DNS Server.

   

7. Click Ok and restart your computer to apply changes.
8. After restarting, launch the game to check if the issue is resolved.
